I've had my S9 for about 20 months now. I recently used it on a long car trip and the battery was completely drained. I then got home, plugged it into the same computer where it has always been plugged into, and... nothing. I tried switching from my normal Linux partition to the Windows dual-boot I have, and still no dice. Finally, I tried my friend's laptop, but it still did not charge. Running lsusb in Linux shows that the kernel is not recognizing the device. I don't know whether the device or the cable is broken. If I slide the switch on the device to turn it on, nothing happens.
